Description
Technical field
The utility model belongs to rail facility field, particularly a kind of for preventing that personnel and larger animal from entering into the guardrail of high-speed railway.
Background technology
High-speed railway is development in recent years a kind of transportation facility faster, there is speed fast, the advantages such as safety height, fast just because of speed, what mostly adopt is power-actuated locomotive, power line has been set up in railroad track top, to railroad track, require also very high, if there is foreign matter to enter into railroad track, will cause a serious accident to the vehicle moving on high-speed railway, if have personnel or larger animal to enter, will cause personnel and haulage vehicle to cause great bodily injury, therefore, in high-speed railway both sides, need to build guardrail, personnel outside railway or larger animal are isolated, particularity due to high-speed railway, the construction of guardrail has also been proposed to special requirement, on the one hand, according to safety regulation, the construction of high-speed railway both sides bans use of crane, again due to the section major part of high-speed railway process in the wild, lack electric power, water source, construction machinery, causes great difficulty to guardrail, simultaneously also very strict to the requirement of guardrail, require guardrail to want firmly, must not adopt thin sheet of metal, once because get loose, field wind-force is larger, wind blows afloat thin sheet of metal can fall rail top electrical network, causes electrical network to damage, to meet simultaneously and be difficult for stolen in the wild and destroy, due to above all objective condition restrictions, caused very large difficulty to the construction of high-speed railway guardrail.
Summary of the invention
Requirement for high-speed railway to railway guardrails of both sides, the utility model proposes the guardrail of a kind of high-speed railway both sides, it is characterized in that: comprise quick base steel plinth, framework, jube; The soil that quick base steel plinth is arranged on railway bed both sides is underground; Two ends, framework bottom are fixedly connected with quick base steel plinth; Jube is arranged in the middle of framework, interval layout, and its jube two ends are fixedly connected with the upper and lower frames of framework respectively; Described quick base steel plinth is that a kind of conical hollow outer wall of steel pipe has screw type lath, head is sharp parts, afterbody is provided with platform and fastener, downward at head, while rotating quick base steel plinth, due to the effect of spiral, base steel plinth can enter in soil fast, form and combine closely with soil, its length determines according to geological condition; Described framework has and has certain thickness steel i iron or channel-section steel is welded to form, and comprises upper transverse frame, lower transverse frame, left munnion, right munnion, pedestal; Upper transverse frame and lower transverse frame are welded on respectively the two ends of left munnion and right munnion, form rectangular frame, and pedestal is welded on respectively the lower end of left munnion and right munnion, for connecting quick base steel plinth; Described jube comprises keel, expanded metal lath, filler; Described keel comprise keelson, exposed keel, and keelson is filled thing and is included in inside, and exposed keel is wrapped in the both sides of jube, for protecting filler, is directly subject to damage; Described expanded metal lath is fixed on keelson and exposed keel, for adhering to filler; Described filler is that rapid solidification slurry is built in a kind of on-the-spot spray, comprise gypsum, cement, sand, granular polystyrene, Plant Powder minces, expanded perlite, property-modifying additive forms a kind ofly has a lightweight, and coagulating property is good, described coagulating property refers to that well setting rate is fast, but can guarantee within the engineering time, to have the characteristic that mobility does not affect construction; And there is microdilatancy and shrink, sturdy and durable, strong with metal binding ability, the feature of corroding metal not.
Beneficial effect
The beneficial effects of the utility model are, can meet high-speed railway requirement to guardrail construction to the requirement of guardrail and high-speed railway simultaneously.

The specific embodiment
Now further illustrate by reference to the accompanying drawings the specific embodiment of the present invention, as Fig. 2, selecting tail diameter is that 80 mm lengths are that the conical hollow steel pipe of 1200 millimeters is as hollow supervisor 13,11 places start at hollow supervisor's 13 external surfaces according to 2 millimeters of 50 millimeters of pitch and corresponding lead angle throat thickness from the head, the spiral lath 12 that width is 20 millimeters, is welded to apart from 300 millimeters of platform 14 bottoms and locates cut-off, makes it to form a hollow screw, side at head 11 places, 12 millimeters of punching diameters; As Fig. 1, selecting width is that the i iron of 100 millimeters is as pedestal 2, its length is 500 millimeters, pedestal 2 has two, selecting width is that i iron or the channel-section steel of 80 millimeters is all 2500 millimeters as left munnion 7 and right munnion 3 its length, one end of left munnion 7 is welded on to the middle part above of pedestal 2, one end of right munnion 3 is welded on to the middle part above of another pedestal 2; Selecting 60 millimeters of wall thickness of width is that the channel-section steel of 3 millimeters is as upper frame 6 and underframe 8, its length is 3000 millimeters, by quick base steel plinth 1 according to being 3000 millimeters along high-speed railway direction, perpendicular to high-speed railway direction, be fixed 4 points of distance of 400 millimeters, respectively by 4 quick base steel plinth 1 according to definite point, with electric hand drill clamping, quick base steel plinth 1 is screwed in underground, until platform 14 is flat with ground; By the two ends of the pedestal 2 of the good left munnion 7 of welding and firm welding after platform 14 on two quick base steel plinth 1 arranging perpendicular to high-speed railway direction aligns, will welding well pedestal 2 use same methods and two other quick base steel plinth 1 firm welding of right munnion 3; By the two ends of underframe 8 respectively with the binding site firm welding of left munnion 7 and right munnion 3 with pedestal 2, the opening upwards of channel-section steel; By the two ends of upper frame 6 respectively with hanging the firm welding of left munnion 7 and right munnion 3, Open Side Down for channel-section steel; From left munnion 7 one sides, start 150 millimeters, interval, according to the direction welding exposed keel 4 parallel with left munnion 7, exposed keel 4 adopts the galvanized steel plain sheet of 0.6 millimeter of wall thickness to be converted into wide 60 millimeters high 35 millimeters U-shaped, during welding, U-shaped opening deviates from left munnion 7,200 millimeters, the base of first exposed keel 4 that distance has been welded and second exposed keel 4 of U-shaped mouthful of welding relative to previous exposed keel 4, and two exposed keels 4 are parallel to each other; Then successively apart from 150 millimeters of intervals, weld 1 pair of exposed keel 4; Between paired exposed keel 4, connect shape and exposed keel 4 same widths 40 mm lengths and be the keelson of 200 millimeters, 500 millimeters, interval is riveted or is welded between two exposed keels 4; By the expanded metal lath 53 of 1 millimeter of aperture 6X8 millimeter of thickness, be cut into width 230 mm wides, 2500 millimeters long, together with riveting with exposed keel 4 with keelson 51 respectively; Inserts 52 mixing and water addings are stirred, and on-the-spot spray is built on expanded metal lath 53, floating surface, and cement mortar is smeared on 52 surfaces of the filler between every pair of exposed keel 4 or other are with color paint, has just formed the construction of single guardrail; On left munnion 7 and right munnion 3, be also provided with connecting hole or joint pin, be conveniently connected with next section guard.Owing to having adopted quick base steel plinth 1, avoided complicated foundation construction, do not need large-scale construction equipment, can meet field construction, due to framework and jube 5 be all disperse after site operation, do not need crane; Because jube is comprised of keel and filler, after having constructed, solid and reliable, durable in use.
